APPARATUS FOR THE MANUFACTURE OF SUGAR, 80C.

SPECIFICATION forming part of Letters Patent No. 343,108,51ated June 1, 1886. Application filed April 27, 1883. Serial No. 93,148. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH A. COOK, of Auburn, county of Cayuga, State of New York,have invented new and useful Improvements in Apparatus for the Manufacture of Sugar, Salt, 820., of which the following is a full and exact description,reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a sectional view of an evaporating-kettle provided with an inclosing-jacket for deflecting the flame over the entire surface of the kettle. Fig. 2 is a similar view showing another form of inclosing-case having aseries of stepped annular rings for asimilarpurpose, and Fig. 3 is asectional view showing the application of my improvement to an evaporating-pan.

In salt and other evaporating apparatus in which fuel of any kind was used as the heating agent, as heretofore constructed,while having been found very desirable under some circumstances, have been open to one very serious objection where a series of such evapora ing kettles or pans were used, as the direct action of the flame could not be brought upon all the kettles or pans with the same regularity or intensity, and as a consequence the evaporation was caused to take place much faster in some of the kettles thanin others.

My invention has for its object the remedying of the defects heretofore existing in this class of evaporators, and consist-ing in the employment of gas as a heating agent, whereby the same may be carried to any number of pans or kettles, and all of said pans or kettles in the series subjected to a uniform heat.

It further consists in the combination,with the main supply-pipe, of laterals provided with cocks, whereby the gas may be cut off from any one or more of the kettles without affecting the others in the series.

It further consists in surrounding the pans or kettles with an inclosin'g-case, and in forming the case in such a manner that it shall defleet the fiame from the gas evenly over the entire surface of the kettle or pau,all as hereinafter explained.

In Fig. 1 an ordinary kettle, A, is shown having an outerjacket or casing, B, conforming in shape thereto, these parts being con nected together so as to leave a space between them similar to that in like apparatus where steam is used as the heating agent. This outer jacket is provided near its upper edge with pipes or discharge-fines O,for carrying off the Vapors or products of combustion of the gas, and is provided centrally with an opening, D, for connecting the gas-pipe therewith.

In Fig. 2 a modification in the form of the casing is shown, in which a series of stepped annular rings,E,are mounted and arranged in such relation to thepipe as to deflect or spread the flame over the entire surface of thekettle.

In Fig. 3, an evaporating-pan is shown resting upon a series of longitudinal bars forming separate compartments under the pan, and through which the gas-pipe is run. This gaspipe is perforated at points between these partition-walls, and is provided with suitable tips for the passage of the gas. These partition-walls are provided with openings near their upper edge,as shown at F, for the escape of the vapors or products of combustion of the gas, and which is allowed to finally escape from the inclosing-case through openings E E,arranged in the end walls of the supporting-frame. The several openings for the passage of the gas are each provided with a cock for regulating the flow of gas and the consequentintensity of the heat, either to the separate kettles or any portion of the pans without affecting the other kettles or portion of the pan. The outer cases or jackets surrounding the kettles or pans may be coated with any suitable non-conducting material, if desired.

Having now described my .invention, I claim 1. As an improvement in the art of manufacturing salt, a series of kettles for containing the liquid, a gas-supply pipe extending from end to endof the same, and an outlet from said pipe under each of said kettles, whereby the kettles are subjected to a regular heat, and a uniform grade of salt obtained throughout the series, as set forth.

2. -In an evaporator, the combination,with the kettles or pans,of the gas-supply pipe,provided with the laterals or burners, and with the cocks for regulating the supply of gas to any of said kettles or pans or portions thereevenly over the entire surface of the kettle,

of without affecting the others of the series, as substantially as described. to set forth. In testimony whereof I have hereunto set my 3. In an evaporator, the combination, with hand this 4th day of April, A. D. 1883. 5 the kettles and with the gas mainor pipe, of JOSEPH A. COOK.
